Amide dendrimer compositions

Abstract

Amide compounds, amide polymers, compositions including amide compounds and amide polymers may be used to bind target ions, such as phosphorous-containing compounds in the gastrointestinal tract of animals. In some cases, amide compounds and amide polymers may include a core derived from an amide polyol and an organic polyacid or ester.

What is claimed is: 
     
       1. A pharmaceutical composition comprising:
 a) at least one amide compound represented by the following Formula I: 
 
       
         
           
           
               
               
           
         
         
           wherein 
           R 3  is independently represented by the following Formula II: 
         
       
       
         
           
           
               
               
           
         
         
           
             wherein 
             p, q and r independently represent an integer from 0-2; 
             R 4  independently represents 
           
         
       
       
         
           
           
               
               
           
         
         
           
             
               wherein 
               m independently represents an integer from 1-20; 
               R 5  independently represents a hydrogen radical; a substituted or un-substituted alkyl radical; a substituted or un-substituted aryl radical; or R 5  and a neighboring R 5  together represent a link or links comprising a residue of a crosslinking agent, a substituted or un-substituted alicyclic radical, a substituted or un-substituted aromatic radical, or a substituted or un-substituted heterocyclic radical; or R 5  represents a link with another compound; 
             
           
         
         b) a crosslinking agent or residue thereof; and 
         c) a pharmaceutically acceptable excipient. 
       
     
     
       2. The pharmaceutical composition according to  claim 1 , wherein the amide compound is represented by the following Formula IV:
